To validate a questionnaire for the diagnosis of orhorexia oervosa, an eating disorder defined as "maniacal obsession for healthy food".
525 subjects were enrolled. Then they were randomized into two samples (sample of 404 subjects for the construction of the test for the diagnosis of orthorexia ORTO-15; sample of 121 subjects for the validation of the test). The ORTO-15 questionnaire, validated for the diagnosis of orthorexia, is made-up of 15 multiple-choice items.
The test we proposed for the diagnosis of orthorexia (ORTO 15) showed a good predictive capability at a threshold value of 40 (efficacy 73.8%, sensitivity 55.6% and specificity 75.8%) also on verification with a control sample. However, it has a limit in identifying the obsessive disorder. For this reason we maintain that further investigation is necessary and that new questions useful for the evaluation of the obsessive-compulsive behavior should be added to the ORTO-15 questionnaire.
验证一份用于诊断“健康食品癖”的问卷，“健康食品癖”是一种被定义为“对健康食品的疯狂痴迷”的饮食失调症。
招募了525名受试者。然后将他们随机分为两个样本（404名受试者的样本用于构建“健康食品癖”诊断测试ORTO - 15；121名受试者的样本用于测试的验证）。经过验证可用于诊断“健康食品癖”的ORTO - 15问卷由15个多项选择题组成。
我们提出的用于诊断“健康食品癖”的测试（ORTO - 15）在阈值为40时显示出良好的预测能力（功效73.8%，敏感性55.6%，特异性75.8%），在对照样本验证中也是如此。然而，它在识别强迫性障碍方面存在局限性。因此，我们认为有必要进行进一步调查，并且应该在ORTO - 15问卷中添加有助于评估强迫行为的新问题。
